Abstract:

Assuring safety is important in autonomous vehicles. The safety related to autonomous vehicles can be primarily viewed from two perspectives: the functional safety (FuSa) perspective and the safety of the intended functionality (SOTIF) perspective. While FuSa ensures the system has an acceptable risk with respect to malfunctions of electrical and electronic components, SOTIF ensures the system has an acceptable risk with respect to functional insufficiencies and performance limitations. ISO 26262 and ISO 21448 are the state-of-the-art international standards used to ensure compliance with FuSa and SOTIF for autonomous automotive systems, respectively. The ISO 21448 standard mentions the need for alignment of ISO 26262 activities with the ISO 21448 activities and describes the mapping at a very high level. However, given the iterative nature of SOTIF activities in ISO 21448, the workflow between the two standards is not a direct one-toone mapping. Hence, we need a clear understanding how we can align ISO 26262 and ISO 21448 activities, and on how analysis done in one standard can impact the other. To achieve this, in this paper we propose a detailed workflow between ISO 26262 and ISO 21448 standards. We discuss guidelines on how to find if a change to design due to SOTIF modification can affect FuSa analysis and vice versa. We also discuss the aspects we need to consider for agile development when we want to ensure the system being

Abstract:

Functional safety is of the utmost importance in the development of safety-critical automotive systems, especially with the introduction of driver assist and automated driving systems. ISO 26262: Functional Safety – Road Vehicles, has been the de facto standard for functional safety in the automotive electronics domain since the release of its first edition in 2011. It is currently available in its second edition, published in December 2018. In this paper, we present an overview of the standard, which applies to all activities during the safety lifecycle of system development. In the concept phase of ISO 26262, the hazard and risk assessment process focuses on identifying possible hazards caused by malfunctioning behavior of electrical/electronic (E/E) safety-related systems and mitigating them through the identification of safety goals. The design phase includes system, hardware, and software development, with requirements developed from the safety goals. ISO 26262 also prescribes the functional safety management activities to be performed during the safety lifecycle and provides requirements for the supporting processes. In addition to presenting an overview of the standard, this paper highlights some major changes introduced in the second edition of ISO 26262.

Abstract:

The popularity of electronic systems had increased in automobiles. A lot of ECUs, electronics sensors, bus are used in automobile systems which has made the system complex. Safety analysis should be done to ensure functional safety. IEC has introduced the standard, ISO 26262 for safety analysis of electrical/electronic/programmable systems in automobiles to reduce and control systematic faults. ISO 26262 give guidelines to define and follow the techniques strategically for the entire product life cycle of the vehicle. It does not explain how functional safety is done but it will guide us throughout the process. In this paper, we have analysed the Automatic Emergency Braking system as per the ISO 26262 guidelines. AEB is a significantly important active safety system which relies on electronic sensors, ECU and electronic actuators. The proper functioning of these electronic components could save the hazard from happening. We have determined the ASIL level, we determine safety goal and safety requirement, Fault Tree Analysis (FTA), Failure mode and Effect analysis. Also, we performed an HW safety analysis.

Abstract:

Safety is always the key issue in automotive industry. The adoption of hi-tech automotive applications requires not only the development of reliable electrical/electronic/programmable electronic (E/E/PE) systems and communication protocols, but also an evolution in functional safety process management. ISO/WD 26262, the adaption of IEC 61508 for road vehicles, provides guidelines and standardized measurements for functional safety. This paper discusses how automotive microcontroller suppliers can deal with this new challenge by integrating functional safety management into product design and development. An ISO/WD 26262-compliant functional safety management flow is proposed, with specifications on techniques of corresponding safety assessment.

Abstract:

In order to ensure safety and reliability, some safety-related electrical and electronic (E/E) systems in vehicles need to be designed as a whole-redundancy system. Although ISO 26262 provides guidance for the analysis of random hardware failure, the problem of estimating whether the safety-related E/E systems, especially whole-redundancy system can meet the index of the ASIL level in ISO 26262 is still unsolved. Fault tree analysis (FTA) is one of the basic methods to analyze random hardware failure of a vehicle’s E/E systems quantitatively. In generic FTA, the quantitative analysis of dynamic logic gates, which usually exist in the fault tree of whole-redundancy system, cannot be calculated. Meanwhile, Markov chain can solve the problem of quantitative calculation of dynamic fault tree, but brings a side-effect of complicating the calculation of static logic gates in fault trees. In order to evaluate random hardware failure of a vehicle E/E system more concisely and effectively, and to estimate if a new safety-related E/E system’s random hardware failure rate can meet the index demand in ISO 26262, this study proposed a mixed model based on FTA and Markov chain. First, the definition of random hardware failure and fault classification were clarified. Then, a mixed model based on FTA and Markov chain was proposed. Finally, a whole-dual-redundancy steer by wire system was used as an example to test the validity of the mixed model. This study not only proposed a new mixed model based on FTA and Markov chain for the calculation of a whole-redundancy system’s random hardware failure rate, but also provided a new quantitative validation method for safety-related E/E systems in vehicles that need to meet the reliability index requirement in ISO 26262.

Abstract:

Modern vehicles are integrating a growing number of electronics to provide a safer experience for the driver. Therefore, safety is a non-negotiable requirement that must be considered through the vehicle development process. The ISO 26262 standard provides guidance to ensure that such requirements are implemented. Fault injection is highly recommended for the functional verification of safety mechanisms or to evaluate their diagnostic coverage capability. An exhaustive analysis is not required, but evidence of best effort through the diagnostic coverage assessment needs to be provided when performing quantitative evaluation of hardware architectural metrics. These metrics support that the automotive safety integrity level—ranging from A (lowest) to D (strictest) levels—was obeyed. In this context, this paper proposed a verification solution in order to build an approach that can accelerate the diagnostic coverage assessment via fault injection in the semiconductor level (i.e., hardware description language). The proposed solution does not require any modification of the design model to enable acceleration. Small parts of the OpenRISC architecture (namely a carry adder, the Tick Timer peripheral, and the exception block) were used to illustrate the methodology.

Abstract:

With the improvement and development in the automotive, the safety related aspects are also becoming more important. Hence there is a stringent demand for the Functional Safety and reliability. In these years, most of the vehicles are made with electrical and electronic components and systems which include lots of Electronic Controller Units (ECUs), electronic sensors, bus systems with coding. Due to the complexity in application of these electrical, electronics and programmable electronics, it is necessary to analyze the potential risk of malfunction for automotive systems. Thus, ISO 26262 has been introduced for automotive electrical/electronic (E/E) systems which ensure the complete safety installation of all ECUs, E/E systems its technical as well as management issues. In this paper, functional safety in accordance with ISO 26262 Part 3 of an electric traction inverter is done, the Functional safety report is generated in MEDINI TOOL and the short circuit fault of traction inverter is considered for Functional safety using MATLAB/SIMULINK.

<div class="section abstract"><div class="htmlview paragraph">ISO 26262, a functional safety standard for motor vehicles, was published in November 2011. Although motorcycles are not included in the scope of application of the current edition of ISO 26262, it is expected that motorcycles will be included in the next revision. However, it is not appropriate to directly apply automotive safety integrity levels (ASILs) to motorcycles because the situation of usage in practice presumably differs between motorcycles and motor vehicles. In our previous study, we newly defined safety integrity levels for motorcycles (MSILs) and proposed that the levels of MSILs should correspond to levels one step lower than those of ASILs; however, we did not investigate the validity of their connections. Accordingly, in this research, we validated the connections. We defined the difference of levels of SILs between motorcycles and motor vehicles as the difference of target values of random hardware failure rates specified in ISO 26262-5. By taking into account the benefits of economy, convenience, and pleasure, it is considered that motorcycle and motor vehicle users accept the results of traffic accidents as upper limits on tolerable risks. Using recent traffic accident results, we compared accidental risks while riding motorcycles or motor vehicles. We demonstrated that the difference of levels of SILs between motorcycles and motor vehicles and the difference of upper limits on tolerable risk between motorcycles and motor vehicles balance each other. It is considered that this finding justifies setting the levels of MSILs one step lower than the levels of ASILs.</div></div>

<div class="section abstract"><div class="htmlview paragraph">ISO 26262 was established in 2011 as a functional safety standard for passenger cars. In this standard, ASILs (Automotive Safety Integrity Levels) representing safety levels for passenger cars are determined by evaluating the hazardous events associated with each item constituting an electrical and/or electronic safety-related system according to three evaluation criteria including injury severity. On the other hand, motorcycles will be included in the scope of application of ISO 26262 in the next revision. It is expected that a severity evaluation for motorcycles will be needed because motorcycles are clearly different from passenger cars in vehicle mass and structure. Therefore, this study focused on severity class evaluation for motorcycles. A method of classifying injury severity according to vehicle speed was developed on the basis of accident data. In addition, a severity table for motorcycles classifying injury severity according to vehicle speed for each accident type was produced using accident data involved with motorcycles in Japan.</div></div>

Abstract:

Safety-critical intelligent automotive systems require stringent dependability while the systems are in operation. Therefore, safety and reliability issues must be addressed in the development of such safety-critical systems. Nevertheless, the incorporation of safety/reliability requirements into the system will raise the design complexity considerably. Furthermore, the international safety standards only provide guidelines and lack concrete design methodology and flow. Therefore, developing an effective safety process to assist system engineers in tackling the complexity of system design and verification, while also satisfying the requirements of international safety standards, has become an important and valuable research topic. In this study, we propose a safety-oriented system hardware architecture exploration framework, which incorporates fault tree-based vulnerability analysis with safety-oriented system hardware architecture exploration to rapidly discover an efficient solution that complies with the ISO-26262 safety requirements and hardware overhead constraint. A failure mode, effect, and diagnostic analysis (FMEDA) report is generated after performing the exploration framework. The proposed framework can facilitate the system engineers in designing, assessing, and enhancing the safety/robustness of a system in a cost-effective manner.

Abstract:

ISO 26262 - The Relevance and Importance of Qualitative and Quantitative Methods for Safety and Reliability Issues Regarding the Automotive IndustrySafety and reliability are key issues of today's and future automotive developments, where the involved companies have to deal with increasing functionality and complexity of software-based car functions. New functionalities cannot only be found in the area of driver assistance - most of the new car functions are and will be safety related as for example in vehicle dynamics control or active and passive safety systems. The development and integration of those functions will strengthen the need of safe processes during the system development. The new upcoming automotive standard on functional safety (ISO 26262), which is derived from the generic functional safety standard IEC 61508 to comply with the specific needs to the application sector of E/E-systems in road vehicles, will provide guidance to avoid the increasing risks from systematic faults and random hardware faults by providing feasible processes and requirements. It is evident that aspects and methods of the safety and reliability engineering are implemented and suited methods are performed in the development process at an early stage. This is one of the requirements of the new ISO 26262, which introduces a so called automotive safety lifecycle to handle all those activities that are necessary to guarantee the functional safety of automotive E/E-systems. In the following, a brief overview of the upcoming automotive standard, its new safety life cycle and the connected activities in order to ensure functional safety for safety related systems will be given. The main aim of this paper is to show the relevance and importance of one of the major tasks within the ISO 26262: the process of the hazard analysis and risk assessment as it is currently performed in the automotive industry. With the help of an example from the automotive sector, the basic steps of this method to determine the automotive safety integrity level (ASIL) are explained. Depending on the ASIL, safety requirements need to be derived as a result of the new standard regarding safety integrity attributes. Furthermore, the connection of the automotive functional safety process with methods for qualification and quantification of safety and reliability issues will be explained in this paper. The Fault Tree Analysis will be used to exemplify one of these methods which are applied subsequent to the hazard analysis and risk assessment and which make a contribution to the validation and verification of the safety process.

Abstract:

With the rapid development of intelligent vehicle safety verification, scenario-based testing methods have received increasing attention. As the space of driving scenarios is vast, the challenge in scenario-based testing is the generation and selection of high-value testing scenarios to reduce the development and validation time. This paper proposes a method for generating challenging test scenarios. Our method quantifies the challenges in these scenarios by estimating the risks based on ISO 26262. We formulate the problem as a Markov decision process and quantify the challenges in the current state using the three risk factors provided in ISO 26262: exposure, severity, and controllability. We then employ reinforcement learning algorithms to identify the challenges and use the state–action value matrix to select motions for a background vehicle to generate critical scenarios. The effectiveness of the approach is validated by testing the generated challenge scenarios using a simulation model. The results show that our method can ensure both accuracy and coverage, and the larger the state space is, the more accident-prone the generated scenarios are. Our proposed method is general and easily adaptable to other cases.
